Symptoms of a transformed migraine
Many people with a history of migraine will suddenly report that the headaches are less severe but are more frequent, until they begin occurring daily. This change may be caused by the daily use of analgesics (pain-relieving medications). These chronic, daily headaches are known as transformed migraines. People usually start getting daily transformed migraine headaches during their 20s and 30s.
Some people report having occasional severe episodes accompanied by nausea and vomiting, much like migraines. Often, it is difficult to differentiate between tension-type headaches and transformed migraines.
